Zstory has continually strived to evolve the manifold to fulfill modern-day customer demands and had made it from 201 (austenitic) 1.25mm stainless-steel for its own protection and longevity. With less pipe welds and a thicker flange specifically trimmed to fit all heads and blocks, it allows for matched porting with improved-flow cylinder heads.

The 6-2 configuration is generally accepted as being the most suitable for the widest range of engine applications.  Zstory has further developed that conception with the 2-1 merging as far back as possible before the first silencer.

The Y-pipe (2-1) collector has a built-in lambda sensor plug and bung to allow accurate engine testing and real-time surveillance and finishes with a V-band clamp fitting to the exhaust line for leak-free and easy mounting/disassembly.

The manifold’s primary pipes have an internal diameter of 40mm. It is important to stress the internal diameter of the pipes because the earlier, cast-iron versions were measured externally and had thicker piping!
